SOUTH BERWICK, Maine — A local firefighter who crashed a 3,000 gallon tanker truck into the woods off Fife’s Lane Sunday afternoon sustained a torn finger ligament, but otherwise escaped serious harm, Chief George Gorman said Monday.

The firefighter, identified as 31-year-old Adam Leach, is a volunteer firefighter with the department. Gorman said the cause of the accident — including whether the crash was caused by a medical condition — is still under investigation. He said the department was awaiting blood tests to rule out drugs and alcohol.

“Other than the cut to his finger he’s fine,” Gorman said. “He was out of the hospital and back here by 6:30 p.m. the same night.” Leach has since been put on unpaid sick leave.

Gorman also mirrored the statements of Assistant Fire Chief Norm Chouinard, who said at the accident scene Sunday that the tanker truck was likely totaled. “There’s some heavy damage,” Gorman confirmed. “The cab is completely destroyed.”

South Berwick previously paid $113,000 for the tanker 13 years ago.

On Sunday, Chouinard said the tanker truck was heading back to the South Berwick fire station after being en route to a chimney fire in Eliot. The driver took Fife’s Road, which is just off Route 236, as an alternate way to get back to the station. He was the only individual in the vehicle.

“It wasn’t an emergency run,” Chouinard said. “He was just using the road to return to the station after getting called off the Eliot fire.”

The tanker crashed in front of 42 Fife’s Lane Sunday afternoon at around 2:15 p.m. Several parts of the vehicle were scattered around the wooded area where the tanker came to rest — which was about 10 yards off the road and halfway down an embankment.

National Wrecker Service arrived to tow the truck from the accident scene. Additionally, the Maine Department of Environmental Protection responded to investigate the potential impact of diesel fuel leaking from the truck.
